Making a decision on which fieldbus technology to implement on industrial automation applications is getting more complicated. During early stages of the design, engineers must choose “Which fieldbus is the right choice for this application”. Properly answering this question ensures the application accommodates both short and long-term needs for the user. This paper explores the basics of digital communications of fieldbus technology. An overview of the traditional and emerging digital communication protocols as well as topology concepts are presented, along with a definition of key terms.
